When using these mini prisms, the measuring points can always be exactly aligned with the measuring instrument and turned through 180 degree. This enables the same survey point to be used from different directions. Bridges, façades and lots of other objects can thus be monitored more quickly and precisely. The integral plug-in system enables prisms to be combined with one another, permitting surveying from different directions without needing to rotate the prism.
Using the mounting plate RSFP-X80, you can easily fix the prisms, even on difficult surfaces, by means of our RSMK-FIX mounting adhesive. After completion of the survey, they can be removed quickly and easily and, if need be, re-affixed.
The mounting plate RSFP-X80is designed in a way so that the prisms can be clipped in – exactly centered – in two directions. The same survey point can thus be used from almost all directions.
If the mounting plate RSFP-X80 is used in high-vibration environments (e.g. if mounted on railway tracks), the prisms can be secured to the mounting plate with small screws.
If necessary, fastening them with screws is also possible.
